One of my favorite facts about middle distance records is that they're all about 17-19 seconds under 60-second pace:
100m: 5.42
200m: 10.81
400m: 16.97
800m: 19.09
1000m: 18.04
1500m: 19.00
Mile: 18.27
2000m: 16.87
3000m: 12.45
2 Miles: 8.70In an ideal world where every record is equally strong, you should see a smooth curve, going up for a while, peaking, and going back down. Aside from small exceptions for factors like the start in sprinting and curve vs. straightaway, this phenomenon is as close to a "law of nature" as you're going to get in our sport.
(In fact, there's nothing special about 60-second pace. Pick your favorite reference pace, and plot world records or your PB paces relative to this pace, and you should see a similar curve).
What we see actually approximates the ideal very, very well! At the short end, the distances are too short to really gain much on 60-second pace, while at the long end, fatigue pulls the pace back. The peak is clearly in the middle, probably somewhere between 800m and 1500m. In fact, judging by the rest of the events, 1000m seems to be just about at the peak of the curve!
This is very suggestive that the 1000m record is probably a bit weaker than most of the others, and that an equally strong record would be around 2:10.7. That estimate certainly isn't definitive, but I do think there's a fair amount of room to drop if someone like Wanyonyi gave it a really good go.
And as a brief follow-up: no one in the history of the world has ever, over any distance, run a race at more than 20 seconds under 60-second pace.
Adjusting for hand times, the first person to go 15 seconds under was...Peter Snell, when he ran 1:44.3 in the 800m in 1962. Since then several thousand people have followed Snell under that barrier, across 6 or 7 events. Somehow I doubt that the 20-second barrier will get as much attention as the 4-minute mile or 2-hour marathon, but it really will be a transcendent accomplishment that covers the whole sport.
